IMPROVEMENT IN WRINGING-M A CHINES.

Specification forming part of Letters Patent No. 194, [71, dated August14, 1877 application filed June 12, 1877.

To all whom it may concern f Be it known that I, NAPOLEON B. PHELPS, ofNew York, in the county of New York and State of New York, have inventedcertain new and useful Improvements in Wringing- Machines; and I dohereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art towhich it appertains to make and use the same, reference being had to theaccompanylng drawings, and to the letters of reference marked thereon,which form a part. of this specification.

My invention relates to wringing-machines; and it consists ina slidingmetallic journal-box having projecting flanges along its inner and outeredges; and, also, in a metallic journalbox having a projection extendingoutside of the frame, and provided with a projecting support or hearingfor the drivinglgear; and in the combination of parts, as will behereinafter more fully set forth.

In the annexed drawings, which fully illustrate my invention, Figure 1is a front elevation of a wringingmachine embodying my invention. Fig.2is a transverse vertical section of the same. Fig. 3 is a longitudinalsection through one end of the machine. Fig. 4 is a perspective view ofthe metallic journal-box.

A A represent the standard or side pieces, connected at the top by across-bar, B, and at the front and rear by other bars or boards, B B,forming the frame of the wrin er. At the foot of the frame is the clampC, for fastening the wringer to the tub. D is the cross-bar on top ofthe journal-boxes, and on top of which lies the spring G, actuated bythe set-screw E. These parts are all constructed and arrangedsubstantially in the same manner as is usual in wringing-machines.

H H represent, respectively, the upper and lower rollers of the wringer,the lower roller H having its journals a resting in the side pieces orstandards A, while the journals 1) of the upper roller B have theirhearings in journal-boxes sliding in said standards.

At one end an ordinary half-box, I, is placed on top of the journal b,said half-box being on its edges provided with vertical ribs or guides,which fit in corresponding gro'oves in the standard. The journals atthis end of the machine are connected by cog-gears J J, as shown. At theother end of the machine is a metal journal-box, L, sliding in thestandard, and the journal I; is placed in a bearing, K, within saidsliding box.

It has been found inpractice that when no other means are used to keepthe moving metal journal-box L in place than ribs or tongues on thesides of the box, which work in grooves in the frame or standard, whenthe great pressure that is necessary for wringing is applied to thesteel spring G, which, when compressed, is lengthened, it crowds thejournal-box outward, which, together with the strain in woi king thecrank, often splits the standard.

To obviate this difficulty I provide the metal I journal-box L withvertical side flanges d d at the inner end, which flaugeswork on theinner surface or surfaces of the standard, and thus have the entirethickness of the standard to resist the outward pressure of the spring.On the outside of the journal-box L, I have also provided similar sideflanges d d, as shown. Although these latter flanges are not reallynecessary in the practical working of the wringer, as the pressure isalways outward, still they are of advantage, as they tend to keep thejournal in its proper position.

The movable metallic journal-box L is, on the outside, provided with adownward-1 ojecting arm, L from which extends the 5 ud L forming abearing for the purchase or crank pinion P, which meshes with acog-wheel, R, secured on the journal 12 of the upper roller H.

The crank bearing or support is thus located on a projection of themoving journalbox, which extends outside of the standard or frame. Thisarrangement admits of the journal of the lower roll being as long as thestandard or frame is thick. Should the journal or bearing of the lowerroll be cut short, so as to allow the projection L of the removablejournal-box L to be placed within the standard or frame, the bearing ofthe roll so shortened would be liable to wear much faster than the otherbearings or journals.

In wringers having a purchase-gear arrangement a counter-shaft withconnecting gears is ordinary employed to transmit the power to therolls; but my present method of applying power first to the upper roll,and through that roll transmit the power to the lower roll by gears fromthe end opposite that to which the power is first applied, obviates thenecessity of using a counter-shaft and its connecting gears withoutdetracting in the least from the merits of the machine, as the double orstep gears J, which connect the two rolls, have two rows of long coarsecogs, which allow the rolls to separate sufficiently withoutdisconnecting the gears. One row of cogs, being set alternately with theother row, virtually form a very fine gear, and the finer the gear theless the friction and the smoother and easier they turn. Having thesedecided advantages, I prefer them to the common or single gears usuallyused on wringers. This arrangement also makes the wringer both lighterand cheaper than when a counter-shaft with connecting gears is employed.1

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a \i'ringing-machine, a movable metallic journal-box having aprojection or projecting arm, L extending outside the frame, andprovided with a stud or bearing, L for the purchase or crank pinion, forthe purposes herein set forth.

2. In a wringing-machine, a metallic journal-box provided with sideflanges d d on the inner side, to bear against the inner surface orsurfaces of the standard, and projection U, with stud L substantially asand for the purposes herein set forth.

3. The movable metallic journal-box L, provided with side flanges d dand d d, and projection U, with stud L substantially as and for thepurposes herein set forth.

4. In a wringin g-machin'e, the purchase driving-gear P, mounted on astud or hearing formed on the arm L of the movable journalbox, said boxextending outside the frame, in combination with the gear R, of largersize, on the upper roll, the step-gears J J on the opposite side of theframe, and the elastic rolls, substantially as and for the purpose setforth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
